Well, this was an awkward anime. My good friend suggested it to me, so of course I became intrigued. It seemed the basic reverse harem start, the female narrating some sort of story, heading to the new venue hosting the love interests. But suddenly I realise they are all vampires, and it's really awkward when they bite her, but you can't help but laugh.
If you like romance animes that are awkward (not always) and a little weird I recommend this. Though I wouldn't recommend taking it too seriously or you'll hate it. It is based on a game so the plot was a little vague compared to it. Enjoy!
